How do I apply for an ABN?

Do I need to register an ABN and a business name separately?

You can register a business name at the same time as your ABN application. If you choose not to register for both at the same time you will need to return to the Business Registration Service to register your business name.

As your registered business name may sometimes be referred to as an Australian business name or trading name, it's important to understand the difference between your ABN and your registered business name. Visit our register your business name page for more information.

I want to register a company. Do I apply for an Australian Company Number (ACN) or an ABN first?

How long does it take to get an ABN?

If your identity cannot be confirmed, or more information is needed, the Australian Taxation Office (ATO) will review your application within 20 business days. They may contact you if they need more information.

My business details have changed. Who do I need to inform?

You must inform the ABR within 28 days of becoming aware of any changes to your ABN registration details. Please note that when you change your business structure you may also be required to register a new ABN.

When you make changes to your business, you may also need to change your business name details. To do this, you must inform the Australian Securities & Investments Commission (ASIC).

How can I find an ABN?

If you want to look up information about a registered ABN, such as to check that your details are up to date or check the details of a supplier, you can do this on the ABN Lookup website. ABN Lookup allows you to search publicly available information supplied by businesses when they register for an ABN.
